The Slope of the line is the rate of change shown in the graph.

Taking two points on the line (1 , 6) and (2 , 12)

Slope (m) is equal to : -

  • [tex] \sf \dfrac{y_2 - y_1}{x_2 - x_1} [/tex]

  • [tex] \sf \dfrac{12 - 6}{2 - 1} [/tex]

  • [tex] \sf \dfrac{6}{1} [/tex]

  • [tex] \sf6[/tex]

Hence, Rate of change is $6 / hour
